GPD 1815430 HVAC A/C Refrigerant Pressure Switch

The GPD 1815430 is a direct-fit OE-replacement HVAC A/C pressure switch designed to restore proper refrigerant pressure monitoring to your vehicle's air conditioning system. GPD (Global Parts Distributors) is a dedicated aftermarket A/C specialist with decades of experience engineering replacement climate control components for a wide range of automotive and heavy-duty applications.

The A/C pressure switch — also referred to as a refrigerant pressure switch or AC pressure sensor — plays a critical role in protecting the compressor and managing system performance. On modern vehicles, it feeds real-time refrigerant pressure data to the Engine Control Module (ECM), which uses that information to regulate compressor clutch engagement. On older vehicles, the switch acts as a direct cut-out to shut down the compressor when pressures fall outside safe operating limits, preventing costly compressor damage from low-charge or over-pressure conditions.

Key Features:

• Direct-fit OE replacement — installs in place of the original switch without modification
• Engineered to meet or exceed original equipment specifications
• Protects the A/C compressor from damage caused by abnormal refrigerant pressure conditions
• Voltage and amp tested for reliable electrical performance and long service life
• Backed by GPD's 1-year limited warranty against defects in materials and workmanship

GPD subjects every pressure switch to rigorous electrical testing prior to shipment, ensuring consistent performance straight out of the box. This switch is a cost-effective, high-quality solution for restoring full A/C system functionality.
